SEALING AND PCURING DEVICE FOR CONTAINERS.

Applicatonrled November 24, 1924, Serial No. 751,835, and in Great Britain December 19, 1923.

This invention has rela-tion to closing and Vsealing means for liquid containers and the like, of that class in which a screwed stopper is fitted rotatively to a screw socket, the stopper and socket being provided with holes or passages to permit the outflow of the con-l tents of thecontainer, when the stopperl is partly unscrewed in the socket, a suitable coinpressible washer being used to provide a liquid tight joint between the end of the stopper and the bottom of the socket, lwhen lthe stopper is screwed home.

The object of the present invention vis to provide means for enabling the contentsof the container to issue at a point well beyond the side or end of the container and the invention accordingly consists in the construction and combination of features v hereinafter more particularly described and claimed.

In the accompanying drawings- Fig. 1 is a central longitudinal sectional view of a stopper and socket embodying my invention, the stopper being shown as closed. Fig. 2 is a similar view with'the stopper in open position.

Figs. 3,V t and modifications. Y.

According to the embodiment of my inven- Y tion illustrated in Figs. 1 and 2 of the drawings, there is provided a screwed stopper 1, having at its inner end a plurality of holes 11, and attached to said inner end a washer 3,-having a corresponding plurality of holes 12, which register with the holes 11. The washer is conveniently attached to the stopper by means of abifurcated rivet 14.

This stopper screws into a correspondingly 5 are sectional views of screw threaded socket 4f, in the bottom of which is a central hole 13. By screwing the 'stopper into the socket its full depth, the washer 3 is caused to cover the hole 13, in thebottom of the socket, as shown in Fig. 1, and thus prevent outflow of the contents of the container.

By unsc-rewing the stopper so .as to remove the washer from the hole 13, as shown in Fig. 2, the oil or other contentsof the container is allowed to pass through the hole 13, and pass out through the holes in the washer and stopper, the rate of outflow being regulated by the degree to which'the stopper' is unscrewed. The washer is made large enough to lit somewhat tightly within the socket so as to form a joint when the stopper isunscrewed, and prevent the oil from leaking out between the socket and stopper along the screw threads.

The socket et extends through al hole in cient to allow the contents to run out through the hole or passage in said stopper.

As illustrated particularly in Figs. 1, 2 and 5 the stopper embodying my invention is of a more elongated form than is usual in the type of stopper, and is formed with a closed outer end and with an outlet or nozzle 15, thereby enablingy the oil or other liquid or fluid to issue at a point well beyond the side or end of the drum or container and in a manner similar to that resulting from the use of a tap. A stopper of this kind lis particularly useful in transferring the contents of the drum or container to vessels or receptacles having somewhat restricted orifices.

On comparing Figure 1 with Figure 2 it will be observed that the outlet or nozzle 15 is so situated. that when the stopper isv screwed tight into the socket't, it extends more or less vertically upwards. By this means any oil or other liquid or lluid which remains in the stopper after the running-off operation, is prevented from dripping therefrom and consequently waste is avoided. rThe outlet or nozzle is, of course, brought into the runningsoff position by unscrewing the stopper tothe desired extent. A cork or equivalent (not shown) attached by a chain or cord to the stopper 1 may be provided for Y insertion into the nozzle or outlet when not in use so as to prevent 'the entrance of dirt, dust or other foreign matter into the intei rior of the stopper, and to this end, the nozzle or outletmay be made tapered.

1f desired, a filter device may be combined with the Stopper 1 or with the socket. For example, as shown in Figures 1, 2, and 5, a iilter 16 formed by a disc of wire gauze or the like may be soldered or otherwise securely 'fixed in the `body of the stopper. Al-

ternately, as shown in Figure 3, the lter device may consist of a dise. 16EL ot wire gauze clamped between a pair of washers 3a secured together by a bitureated rivet or in any other suitable manner. This device is formed to litI tightly on the bottom et the socket l. The washers 3EL may be provided with a series ot holes 12a registering with a corresponding series ot holes 5 in the sock et, in which case the stopper 1 will be turnished with a central hole 2. Or it desired, the washers 8 may be termed with central holes for use with a stopper and socket having` a series of holes and a central hole respectively.

Figure et shows the invention applied to a screwed plug 17 or equivalent tor use in barrels, kegs and the like, said plug` being Jformed with a screwed socket la in which is iXed a plate 18 provided with a plurality of holes 5a. A leather or other washer 3b having holes 12b therein corresponding to the holes 5fL is inserted in the socket over the plate 18 and the screwed stopper 1fL provided with a central hole 2a is screwed into the socket. rThe stopper may be provided with notches 19 to enable it to be rotated by means ot a bar or key. Or a central hole may be formed in the plate 18 and washer 3b and a series ot holes in the stopper. It desired the washer 3b may be fixed to the stopper by means ot a rivet in the manner previously described. The elongated form ot stopper shown in Figures 1 and Q may ot course be used in the arrangement just described.

The devices herein described may be used :tor closing and sealing drums or containers prior to sale and during transit. 1n each case the stopper would be screwed tightly into the socket and secured by a wire passed through holes, notches or slots in the stopper and through one or more lugs or eyes (not shown) on the drum, or container.

Instead ot using' the drawing-oit7 stopper as a closure and sealing member, a screw stopper without any hole or passage therethrough may be employed 'tor this purpose in conjunction with either a plain disc oit leather or other suitable material or a washer in the socket, this stopper being screwed in tightly and sealed as aforesaid. 1n this event a drawing-oill stopper with or without a washer as the case may be, would be supplied separately with the drum or the like and would be used atter the drum had been opened by removal of the sealed stopper and disc it the latter be provided temporarily in lieu of a washer. This method admits ot a short compact stopper being used during transit and storage and a longer stopper being used tor drawing-oit, the advantage of the longer stopper being that the contents when being delivered are prevented trom ruiming down the outside otl the drum or its support.

The short stopper is less likely to suffer damage during transit than would be the longer one which has a greater project-ion trom the drum.

rilhe socket is preferably inserted and fixed in theV drum or container so as net to project on the outside ot same. 1 may use a socket and sealing disc construction the same as or similar to that described in the aforesaid specification and insert the sealing disc without holes so that it acts as a seal to guard the contents in the known manner. 1n order to use a drawing-oil stopper in this case, it would only be necessary to make one or more holes in the sealing disc by piercing same with a nail or suitable instrument and then insert the drawing-oit stopper and its associated washer into the socket. Care would have to be taken in piercing` the seal that the hole or holes formed in said disc did not register with the holes or hole in the washer andstopper. When the stopper was screwed into the socket the washer would be pressed against the pierced sealing disc to shut oi flow of the contents.

According to a further form ot the invention, the closing, sealing and drawingoil:a means may be supplied as an independent unit in which any one ot the constructions previously described with reterence to Figures 1 to 3, may be employed for use with a drum or container having an outlet nozzle ot the type shown in Figure 5, i. e. ot the kind normally closed by a cork or plug, and means may be provided for attaching said unit to the outlet.

Conveniently and as shown in Figure 5, an arrangement ot this nature comprises a stopper 1 ot the form previously described with reference to Figures 1 and 2 screwed into the socket 4t which in this case is provided with a wider lange 7al for the reception ot the means tor attaching the unit to the beaded outlet 20. Said fastening means may comprise a plurality ot screw-threaded hooked members 21, e. g. tour, fitted with wing nuts 22 or equivalent devices, said members being passed through holes in the flange so as to engage the bead 23 when the socket has been placed ,in the outlet; and when the nut devices are tightened up to form a joint between the socket and the nozzle. A leather washer 24; orother suitable packing piece is provided between the flange 7 and the bead 23 to prevent leakage of the contents of the drum or container.

A socket t :tormed with a tlangeTa having holes therein is also adapted for use in a wooden barrel or keg since, it may be inserted in the usual bung hole and secured in position together with a packing piece by nails or screws driven through the holes in the flange into thewood. This socket together with the necessary stopper and washer or a filter device may be used for closing and sealing the barrel or keg prior to sale and during transit or the unit may be supplied independently.

lvhat l claini then is l. Closing, sealing` and drawing-off means for containers for liquids and other substances comprising, in combination, an elongated screwed stopper having a permanently closed outer end and a hole in its inner end, an outlet nozzle on said stopper, a screwed socket which receives the stopper and has a hole therein which is out of register with the hole in the stopper, and a coinpressible washer having a hole in it which registers with one of the aforesaid holes, said washer foniing a joint between the stopperY and the socket when the stopper is screwed down for the purpose specied. y

2. Closing, sealing and drawing-off Ineans for containers for liquids and other substances, comprising, in combination, an elongated screwed stopper having a closed outer end and a hole in its inner end, a screwed socket which receives said stopper and has a hole therein which is out of register with the hole in the stopper, a tapered nozzle on the stopper at or near the closed end thereof, said nozzle extending substantially upwards when the stopper is screwed down, and downwards when the stopper is partly unscrewed in the socket, and a compressible washer having a hole therein which registers with one of the aforesaid'holes, said washer forming a joint between the socket and the stopper when the latter is screwed down, for the purpose specified.

In testimony whereof I aiiix my signature.V
